## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `recent_cfr_changes`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Most recent detected changes to CFR text (title, part, name, dates), newest first. No API key required.
```

### `rules_amending`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Which final rules amend a CFR part or section, read from each rule's own amendatory instructions ("Amend § 52.2120 by..."). Returns the rules, the sections each addresses, and dates. This reports what a rule SAYS it amends — it is not an attribution of any observed text change to that rule. Covers 2020-present; absence means not indexed, not that no rule amended it. No API key required.
```

## Only reads (8)

Looks things up and changes nothing. Claude Code: allow.

### `get_provision_history`

- The name "get_provision_history" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Documented change history for a CFR provision by canonical id (e.g. "21-cfr-1304.04(a)"): before/after text, computed redline, observed dates, and candidate final rules. 404 when the provision is not in the documented-change set — absence of a documented change is not a claim that nothing changed. No API key required.
```

### `get_requirement`

- The name "get_requirement" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Detail for one extracted obligation by id, including its source rule and citation URL. Requires an API key.
```

### `get_rule_comments`

- The name "get_rule_comments" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Public comments for a Federal Register document (organization, title, date, body where available). Coverage is partial and stated in the response. Requires an API key.
```

### `get_stats`

- The name "get_stats" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Aggregate corpus statistics: documents, obligations, pairs, agencies, coverage dates. No API key required.
```

### `list_obligations`

- The name "list_obligations" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List extracted regulatory obligations ("who must do what") with filters: agency, deontic class, free text. Obligations are machine-extracted with quality tiers; they are not legal advice. Requires an API key.
```

### `list_rules`

- The name "list_rules" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List Federal Register documents with filters: agency slug, document type, rulemaking pathway (interim_final/temporary/direct_final = notice-and-comment bypass classes), or docket id. Requires an API key.
```

### `lookup_provision`

- The name "lookup_provision" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a CFR provision by citation (e.g. "21 CFR 1304.04") or by an exact quotation, optionally as of a past date. Returns the provision text with a ProvisionEvidence object (source, snapshot date, hashes). Explicitly reports ambiguity or no-match instead of guessing. Requires a free API key.
```

### `search_regulations`

- The name "search_regulations" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full-text search over Federal Register documents and extracted obligations (FTS5/BM25). Totals are approximate (total_exact: false). Requires an API key.
```
